<p>HIGH VOLTAGE CIRCUIT INTERRUPTER SWITCH ARRANGEMENT A high voltage circuit interrupter is enclosed within an integral insulating housing that includes an operating mechanism enclosing portion, an insulator portion, and a muffler portion. The integrally formed insulating housing is formed to provide a groove in one interior wall of the operating mechanism enclosing portion and a similar groove is formed on the housing cover immediately opposite the groove in the wall so that a portion of the operating mechanism can ride in the grooves thereby eliminating certain internal metallic components. The operating shaft of the interrupter is hexagonal in cross section thereby eliminating the need for special machining, keys, and cross pins to attach operating levers to the shaft. Operating triggers having round bearing surfaces are inserted over the ends of the hexagonal shaft to provide a smooth running bearing fit with openings in the housing wall. A unique locking arrangement is utilized to lock the lever arm of the operating mechanism to the hexagonal shaft. Also, a bayonet type connection at the exhaust end of the interrupter unit permits a rain cap to be easily and conveniently attached to the interrupter unit.</p> |
